Nether roof/ elytra momentum/ horrible death glitch

I was gliding through the my Nether tunnel (2 wide, 3 tall, around y100, with packed ice every other block one block above the normal floor level), when I accidentally stopped gliding for a few seconds. I resumed gliding, when I noticed that my elytra was continuing to use my momentum from my previous rocket. I used another midway through the boost from the first one, and ended up being slammed against the ceiling. hitting the ceiling in a tunnel on an elytra has never caused me any problems before, but this time, I died from "kinetic energy".  I know this is a normal death message when hitting blocks head on at high speeds, but I was still going parallel to the roof, despite being shoved into the ceiling. I rejoined the world, and I was stuck crawling for a few seconds. I returned to the spot of my death and found out by making a creative duplicate of my world that my items equipped on my body, in my off and main hands, and my experience ended up above the nether roof. I cannot upload a world for the recreation of this, due to the fact that world uploads aren't available from Xbox (maybe you could fix that too?),but I have attached a photo. This was one of my only elytras, and basically all of my Netherite armor, which was fully enchanted. 

 

Any help would be GREATLY appreciated!!!
